Intersecting 2 roofs in AC15?

Anonymous — Tue, 23 May 2023 12:49:03 GMT

Hi,
In the attached image I am trying to intersect roof #2 which is a single plane roof with roof #1 which is multi plane (AC15 roof kind) by selecting roof #1 and (choosing roof tool) Command click edge of roof #2 and it does not intersect them. What has changed in AC15?
Thanks,
Joseph

Instead command+click you have to use Connect now if at least one element is polyroof (it is something like SEO). Extend roofs to intersect them and then use this method.

Hi,
I intersected and use SEO yet non of the "choose operation:" worked, any other thoughts?
Thaks,

I think here you should make that single plane part of the Complex Roof it connects to.
See how the Pivot Lines of the Complex Roof now go and how two roof planes of that right part are set to Gable.

How do I make the single plane part of the complex roof?
Thanks

See the image I posted.
Note the Pivot Lines. This is what I have drawn. The Multi-plane Roof was generated.
Then not the two sides where it says: gable with zero overhang.
Click each of those edges, choose the Gable radio button (which in effect will erase that roof plane), and set its overhang value to zero.
This was my solution.

Thank Laszlo, I was able to get it to this extent but have hard time extending the roof in the middle to the roof to the left to get the same effect you show. Could you guide me further?
Thanks,
Joseph

I think Laszlo is suggesting you edit the polyroof on the left, adding geometry to it to replace the single roof.

An alternative might be to (make a copy of polyroof and) convert the polyroof to individual elements, then extend your "roof 2". (If you made a copy before exploding it, you could then delete the copy). Just putting it out there - haven't installed 15 just yet, so there's a good chance I'm talking rubbish.

Editing the polyroof would be just too cumbersome for doing an opration which in AC14 use to take few second; he must have extended the roof on the right to left a lot faster, just do not know how ?

Pet palette / magic wand takes no time at all.

How does this Extend the right roof to left at line of their intersection, pet palette helps if you know where they are going to intersect?

I think Laszlo like me was thrown a bit by the angle of your 3D image.
It is actually 2 main buildings joined together by a corridor I think.
No gables or flat roofs involved.

The easiest solution would be to add an entirely new multi-plane roof over the entire structure.

If that is not an option then I would delete the single plane roofs and and another multi-plane roof here with hip ends.
Then stretch that across so it overlaps the main roof and then use the "connect" option to join them.

Or you could simply add two new nodes to the pitching line of the main roof on the left (so it is in 3 sections) and then stretch the middle section out over the corridor.
Then you can connect it to the roof on the other side.

Failing that then convert all roofs to single plane and trim them up as you would have in 14.

Actually it can be done simply with your single plane roof connected to the multi-plane roof.
Just stretch them so they over lap and then "Coonect" them.

If they look fine in 3D but not in 2D there is a setting in "Preferences" that you can adjust.
See my next post.

First stretch your single plane roofs and "connect" them to the multi-plane roof.

After the connection if it still looks the same in plan as it did befor then go into OPTIONS menu > PROJECT PREFERENCES > CONSTRUCTION ELEMENTS.
Turn on the option for "True 3D projection".

Re: Intersecting 2 roofs in AC15?

Barry Kelly — Tue, 19 Jul 2011 03:11:36 GMT

Your roof will now look like this in plan.

I always forget about this option.

Oops. I forgot about that preference option.
This is why I suggested the one multi-plane roof approach.
But it seems like it is not necessary.

Thanks Barry I followed the method of Multi-Plane Hip Roof, looks good in 3D but in 2D the dash lines at intersection of roofs are missing and the setting in OPTIONS menu > PROJECT PREFERENCES > CONSTRUCTION ELEMENTS.
Turn on the option for "True 3D projection". does not make any difference?
Thanks,
Joseph

I am not sure why they don't show properly in plan then.
That preference option has no effect on multi-plane roofs - they automatically appear in 2D as they do in 3D (or they are supposed too!).

It only affects the single plane roofs - by default connections (SEO) to these do not show in plan - just as in version 14 and before.
But now we can make them appear in 2D as they do in 3D as well with this option.

Here is an image of 3 multi-plane roofs simply connected.
I did nothing else to them at all.

If you could tell me please if you used:
Single Plane Roof
or
Muli-Plane Hip roof
or
Multi-Plane Gable roof
for the roof located Between two larger roofs?
Thanks,
Joseph

Multi-plane hip and I changed the ends to gable.
But multi-plane gable would work too.

The single roof planes also work so long as the preference is set for true 3D.
